  1. Profitability Analysis of Components of Operating Income An Application of the Horngren, Datar and Foster (2006) Methodology ACCT 5301 May 26, 2012

  2. Decomposing Changes in Operating Earnings • Horngren et al. (2006) argue that changes in operating earnings reflect the strategic considerations of managers’ decisions. • Why should we analyze changes in earnings? Managers need to measure whether a strategic initiative is successful by evaluating its impact on changes in operating earnings.

  3. Firm Strategy Choices • Product differentiation. A firm competes on the basis of product characteristics. • Low cost leadership. A firm competes on the basis of low output prices.

  4. Southwest Airlines • How does Southwest compete? Low costs! “. . . . One of Southwest’s primary competitive strengths is its low operating costs. Southwest has the lowest costs, adjusted for stage length, on a seat mile basis, of all the major airlines. Among the factors that contribute to its low cost structure are a single aircraft type, an efficient, high-utilization, point-to-point route structure, and hardworking, innovative, and highly productive Employees . . .” (Southwest Airlines 10-K, February 17, 2007, page 1). • This has implications for what drives Southwest’s changes in operating income.

  5. Southwest Revenue and Expense Data 2003 2004 Revenues $5,937,000,000 $6,530,000,000 Expenses: Personnel-related $2,224,000,000 $2,443,000,000 Trip-related $1,250,000,000 $1,410,000,000 Aircraft-related $ 997,000,000 $1,068,000,000 Other $ 983,000,000$1,055,000,000 Operating income $ 483,000,000 $ 554,000,000 Difference $ 71,000,000 increase

  6. The Horngren, Datar and Foster (2006) Strategic Analysis of Operating Income • Allows the comparison of one period operating results to those of any future period. • Components: • Growth. • Price-Recovery. • Productivity. • These components relate to cost leadership, product differentiation and growth aspects of a firm’s strategy.

  7. Growth Component • Growth component– the impact on operating income attributable solely to changes in the quantities of outputs sold between periods. • Growth affects both revenues and costs; hence, we have a growth metric for revenues and a growth metric for expenses. • Measures are computed for each input and each output. • The net growth component measures the change in operating income as the difference between the change in revenues due to growth and the growth-related changes in expenses.

  8. Price-Recovery Component • Price-Recovery component– the impact on operating income attributable solely to changes in the prices charged for outputs and prices paid for inputs. • Price-recovery affects both revenues and costs; hence, we have a price-recovery metric for revenues and a price-recovery metric for expenses. • Measures are computed for each input and each output. • The net price-recovery component measures the change in operating income as the difference between the change in revenues due to changes in prices and the changes in expenses due to changes in unit costs.

  9. Productivity Component • Productivity component– the impact on operating income attributable to changes in the use of inputs (either different levels of inputs, a different mix of inputs, and/or changes in capacity) relative to the inputs used in prior periods. • Productivity affects only inputs; hence, we have a productivity metric only for expenses. • Measures are computed for each input. • The net productivity component measures the change in operating income as the sum of the productivity components for each input.

  10. Predictions • Southwest’s stated strategy is to operate as a low-cost air carrier. • As a low-cost carrier, Southwest would be expected to: • Keep its fares relatively low, even in the face of input price increases. • Focus on improving the productivity of its workforce and aircraft. • With low fares and aggressive expansion of its route structure, Southwest should grow its revenue passenger-miles. • Southwest should report: • a favorable aggregate growth component, • A possibly unfavorable aggregate price-recovery component, and • a favorable productivity component.

  11. Southwest’s Revenue and Expense Categories • Total operating revenues. • Expense categories: • Salaries, wages and benefits (personnel-related). • Fuel and oil (trip-related). • Maintenance materials and repairs (aircraft-related). • Agency commissions (trip-related). • Aircraft rentals (aircraft-related). • Landing fees and other rentals (trip-related). • Depreciation (aircraft-related). • Other operating expenses.

  12. Selected Output and Input Measures • Revenues ― Revenue passenger-miles (output). • Personnel-related expenses ― Number of employees (input). • Trip-related expenses ― Number of trips (input). • Fuel and oil. • Agency commissions. • Landing fees and other rentals. • Aircraft-related expenses ― Number of seats of capacity (input). • Maintenance materials and repairs. • Aircraft rentals. • Depreciation. • Other operating expenses ― Number of seats of capacity (input).
